Messages sorted by: [ date ] [ thread ] [ subject ] [ author ]

With linux-5.13 and linux-5.14, the internal drive and SD card reader are gone from the XO-1.5. I bisected the issue to come up with ea718c699055:

# first bad commit: [ea718c699055c8566eb64432388a04974c43b2ea] Revert "Revert "driver core: Set fw_devlink=on by default""

The /dev/mmcblk* nodes are not generated since this patch.

Please find the output of lspsi -vv and lshw below.

I will be happy to provide more info and/or test patches.

Thank you,
Andre Müller
